Highly rigid Milling chuck for resistance against chatter. The BIG original slit mechanism supports high power and high-precision endmilling from heavy cuts to fine cuts.
A unique BIG slit shape is adopted to achieve both the essential runout accuracy and gripping force which are the key elements of a milling chuck. Stable clamping is possible due to sufficient elastic deformation and the ability to remove oil film from the tool shank.
Allows the reliable use of straight collets as well as boring bars, arbors such as face milling cutters. Also optimal as a basic holder.
